[0030] The core of this utility model is to provide a quick-release structure and suspension module for a suspension module in a lower limb rehabilitation training device.

[0031] Please refer to Figures 1 to 3 .

[0032] The quick-release structure for the suspension module in the lower limb rehabilitation training equipment provided by this utility model includes a connecting block 1, a quick-release hole 6, and a quick-release button 4. One end of the connecting block 1 is connected to the suspension rope 8, and the other end of the connecting block 1 has a C-shaped structure with a through hole 2 and an opening 3. The quick-release hole 6 is located at the end of the strap connection part 7 near the connecting block 1. The quick-release button 4 is inserted into the quick-release hole 6, and a groove 5 is provided circumferentially on the quick-release button 4. The groove 5 is matched with the opening 3 so that the connecting block 1 is locked with the quick-release button 4 in the vertical state and separated from the quick-release button 4 in the horizontal state.

[0033] Specifically, one end of the connecting block 1 is connected to the suspension rope 8, and the other end has a C-shaped structure forming a through hole 2 and an opening 3. The strap connection part 7 has a quick-release hole 6 near the end of the connecting block 1. The quick-release button 4 is inserted into the quick-release hole 6, and a groove 5 is formed along its circumferential edge. The groove 5 mates with the opening 3. When the connecting block 1 is in a vertical position relative to the quick-release button 4 (e.g....), Figure 2 (As shown by the dashed line), the opening 3 and the groove 5 cooperate to lock the connecting block 1 and the quick-release button 4. At this time, the suspension rope 8 and the strap connection part 7 are firmly connected; when the connecting block 1 is in a horizontal state relative to the quick-release button 4 (as shown by the dashed line), the opening 3 and the groove 5 cooperate to lock the connecting block 1 and the quick-release button 4. Figure 2 As shown in the diagram, the connecting block 1 separates from the quick-release button 4, facilitating the quick disassembly of the suspension rope 8 and the strap connection 7. This structure enables convenient and quick connection and disassembly of the suspension rope 8 and the strap connection 7, improving ease of use.

[0034] The suspension module in the aforementioned lower limb rehabilitation training equipment uses a quick-release structure. Through the cooperation of the connecting block 1, quick-release button 4, and groove 5, the suspension rope 8 and the strap connection part 7 can be quickly connected and separated. This quick-release structure facilitates the operation of medical staff during the patient's on- and off-machine process, improves work efficiency, and also enhances the practicality and safety of the equipment.

[0035] The quick-release structure for the suspension module in the lower limb rehabilitation training equipment provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0036] In one specific implementation, reference is made to... Figures 1 to 3 The shaft end of the quick-release button 4 is larger than the opening 3. When the connecting block 1 is in a horizontal state, the through hole 2 is concentric with the shaft end of the quick-release button 4.

[0037] Specifically, the shaft end size of the quick-release button 4 is larger than the opening size 3. When the connecting block 1 is in a horizontal state, the through hole 2 is concentric with the shaft end of the quick-release button 4. This allows the connecting block 1 to lock with the quick-release button 4 in a vertical state, ensuring a stable connection between the suspension rope 8 and the strap connection 7, providing a reliable connection for patient suspension. In a horizontal state, the connecting block 1 can be separated from the quick-release button 4, enabling quick disassembly of the suspension rope 8 and the strap connection 7, facilitating patient access to and from the machine.

[0038] It should be noted that the above-mentioned horizontal and vertical states are relative to the quick-release button 4. Therefore, the relative states of the two can be changed by rotating the quick-release button 4, thereby achieving quick release and locking.

[0039] Based on any of the above embodiments, refer to Figure 1 The strap connection part 7 has a mounting groove on the side near the connecting block 1 so that the C-shaped structure is placed in the mounting groove and mates with the groove 5.

[0040] Specifically, a mounting groove is formed on the side of the strap connection 7 near the connecting block 1. The C-shaped structure of the connecting block 1 is placed in the mounting groove, and the C-shaped structure mates with the groove 5 on the quick-release button 4. This allows for a reliable connection and fit between the connecting block 1 and the strap connection 7. When a quick-release operation is required, the connecting block 1 and the quick-release button 4 can be separated or locked more easily, improving the stability and ease of operation of the suspension module's quick-release structure.

[0041] Based on any of the above embodiments, refer to Figure 1 A reset component is provided inside the quick-release hole 6 so that the quick-release button 4 is pressed and rebounds inside the quick-release hole 6.

[0042] Furthermore, the reset assembly includes a spring 9 sleeved on the quick-release button 4, and an annular abutment block is formed on the side of the mounting groove near the button cap of the quick-release button 4. The annular abutment block is clamped in the quick-release button 4, one end of the spring 9 abuts against the button cap, and the other end of the spring 9 abuts against the annular abutment block.

[0043] Specifically, spring 9 is fitted onto quick-release button 4. An annular abutment block is formed on the side of the mounting groove near the button cap of quick-release button 4, clamping quick-release button 4. One end of spring 9 abuts against the button cap, and the other end abuts against the annular abutment block. When quick-release button 4 is pressed within quick-release hole 6, spring 9 is compressed; when the pressure is released, spring 9 rebounds, causing quick-release button 4 to return to its original position. This ensures that quick-release button 4 automatically rebounds after being pressed within quick-release hole 6, guaranteeing the smoothness and stability of the quick-release mechanism and improving the user experience.

[0044] Based on any of the above embodiments, refer to Figure 1 and Figure 3A limit structure is provided between the quick-release button 4 and the quick-release hole 6 so that the quick-release button 4 is limited to the quick-release hole 6.

[0045] Furthermore, the limiting structure includes a threaded hole 10 opened at the end of the quick-release button 4 away from the button cap, a limiting bolt is provided in the quick-release hole 6, and the limiting bolt is sequentially threaded to the threaded hole 10 and the side wall of the quick-release hole 6.

[0046] Specifically, the quick-release button 4 has a threaded hole 10 at the end furthest from the button cap, and a limiting bolt is installed in the quick-release hole 6. The limiting bolt is sequentially threaded into the threaded hole 10 and the side wall of the quick-release hole 6. This allows the limiting bolt to further restrict the position of the quick-release button 4 within the quick-release hole 6, preventing the quick-release button 4 from coming out of the quick-release hole 6. This ensures the stability and reliability of the quick-release structure during use, thereby improving the stability of the connection between the suspension module and the strap connection part 7, which is beneficial for the normal operation of the equipment for rehabilitation training.

[0047] Based on any of the above embodiments, refer to Figure 1 and Figure 2 The end of the connecting block 1 away from the C-shaped structure has a horizontally opened suspension hole 11, and the suspension rope 8 passes through the suspension hole 11 in a U-shape and is fixed to the connecting block 1.

[0048] Specifically, a suspension hole 11 is horizontally provided at the end of the connecting block 1 furthest from the C-shaped structure. The suspension rope 8 passes through the suspension hole 11 in a U-shape and is fixed to the connecting block 1. This makes the connection between the suspension rope 8 and the connecting block 1 more stable, and during the operation of the suspension module, it can more reliably transmit force to the strap connection part 7, providing stable suspension support for the patient, reducing the possibility of loosening or detachment during suspension, and improving the safety and reliability of the equipment.

[0049] Based on any of the above embodiments, a wear-resistant layer for preventing wear is provided inside the suspension hole 11.

[0050] Specifically, a wear-resistant layer is provided inside the suspension hole 11, directly contacting the suspension rope 8 that passes through it. When the suspension rope 8 moves in a U-shape through the suspension hole 11, the wear-resistant layer effectively prevents direct friction between the suspension rope 8 and the suspension hole 11, thus preventing wear of the suspension rope 8 due to friction and ensuring the reliability and service life of the suspension module. The wear-resistant layer can be a rubber or ceramic coating, extending the service life of the suspension rope 8.

[0051] The implementation principle of the quick-release structure for the suspension module in a lower limb rehabilitation training device according to this application embodiment is as follows: This quick-release structure, through the cooperation of the connecting block 1, the quick-release button 4, and the groove 5, enables the rapid connection and separation of the suspension rope 8 and the strap connection part 7. The reset component and limiting structure ensure the normal operation and stability of the quick-release button 4, while the wear-resistant layer protects the suspension rope 8. This quick-release structure facilitates the operation of medical staff during patient on- and off-machine procedures, improves work efficiency, and also enhances the practicality and safety of the equipment.

[0052] The lower limb rehabilitation training device provided by this utility model includes a suspension module comprising a suspension rope 8 and a strap connection part 7 connected to the suspension rope 8. A quick-release structure is provided between the suspension rope 8 and the strap connection part 7, which is the quick-release structure described above. The quick-release structure is installed between the suspension rope 8 and the strap connection part 7, allowing for quick connection or separation of the suspension rope 8 and the strap connection part 7 when needed. This makes the suspension module more flexible and convenient in actual use. When patients are on and off the device, medical staff can quickly complete the connection and separation operations of the suspension rope 8 and the strap connection part 7, saving time and manpower. At the same time, the reliability of the quick-release structure ensures the safety of the suspension module during patient rehabilitation training and improves the overall efficiency of the rehabilitation training device.

[0053] The structure of the other parts of the suspension module is described in reference to existing technologies and will not be repeated here.

[0054] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
